Dolphins have once again proven that they are one of the smartest animals on Earth.

Wildlife researchers spoke about a new unusual hunting method that they managed to spy on dolphins from Florida. The essence of the method is that the dolphin lifts sand from the bottom and stirs up the water strictly in a circle. Continuing to make circles, he reduces their diameter.

After this, all that remains for the dolphin to do is wait with its mouth open. Small creatures at the bottom are frightened by the sandstorm and try to climb higher.
